Membership in the Alden Kindred is open to all individuals, families and business organizations. There are two basic types of membership: Kindred and Museum.

Kindred members can trace and document their ancestry to John and Priscilla (Mullins) Alden while their non-descendant spouses and adopted children can join as Associate Members.

Museum members are those individuals who cannot or have not traced and documented their ancestry to John and Priscilla but who still wish to help preserve a most important landmark, the Alden House Historic Site and the precious heritage it represents.
